First record of the genus Pseudopilolabus Legalov, 2003 (Coleoptera: Attelabidae) in Dominican amber

Creator:: Poinar, George O., Jr., Brown, A. E., and Legalov, A. A.
Abstract:: A new weevil species (urn:lsid:zoobank.org: act:2D5E9E4A-A250-4D0A-AF69-CF4753436686), Pseudopilolabus othnius Poinar, Brown and Legalov, sp. nov. (Coleoptera: Attelabidae), is described from Dominican amber. The new species is close to the extant P. viridanus (Gyllenhal, 1839) and P. splendens (Gyllenhal, 1839) but differs by having a bronzed body, narrower and more convex elytral...

Eocene and not Cretaceous origin of spider wasps: Fossil evidence from amber

Creator:: Rodriguez, Juanita, Waichert, Cecilia, von Dohlen, Carol D., Poinar, George, Jr., and Pitts, James P.
Abstract:: Spider wasps had long been proposed to originate in the mid-Cretaceous based on the Burmese amber fossil Bryopompilus interfector Engel and Grimaldi, 2006. We performed a morphological examination of this fossil and determined it does not belong to Pompilidae or any other described hymenopteran family. Instead, we place it in...

A Phylogenetic Perspective on the Individual Species- Area Relationship in Temperate and Tropical Tree Communities

Creator:: Yang, Jie, Swenson, Nathan G., Cao, Min, Chuyong, George B., Ewango, Corneille E. N., Howe, Robert, Kenfack, David, Thomas, Duncan, Wolf, Amy, and Lin, Luxiang
Abstract:: Ecologists have historically used species-area relationships (SARs) as a tool to understand the spatial distribution of species. Recent work has extended SARs to focus on individual-level distributions to generate individual species area relationships (ISARs). The ISAR approach quantifies whether individuals of a species tend have more or less species richness...

How Effective Are DNA Barcodes in the Identification of African Rainforest Trees?

Creator:: Parmentier, Ingrid, Duminil, Jérôme, Kuzmina, Maria, Philippe, Morgane, Thomas, Duncan W., Kenfack, David, Chuyong, George B., Cruaud, Corinne, and Hardy, Olivier J.
Abstract:: Background: DNA barcoding of rain forest trees could potentially help biologists identify species and discover new ones. However, DNA barcodes cannot always distinguish between closely related species, and the size and completeness of barcode databases are key parameters for their successful application. We test the ability of rbcL, matK and...

Tapeworm Eggs in a 270 Million-Year-Old Shark Coprolite

Creator:: Dentzien-Dias, Paula C., Poinar, George, Jr., de Figueiredo, Ana Emilia Q., Pacheco, Ana Carolina L., Horn, Bruno L. D., and Schultz, Cesar L.
Abstract:: Remains of parasites in vertebrates are rare from the Mesozoic and Paleozoic. Once most parasites that live in - or pass through - the gastrointestinal tract of vertebrates, fossil feces (coprolites) or even intestinal contents (enterolites) can eventually preserve their remains. Here we announce the discovery of a spiral shark...

The VAMOS Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx): goals, platforms, and field operations

R., Chaigneau, A., Toniazzo, T., Minnis, P., Palikonda, R., Abel, S. J., Brown, W. O. J., Williams, S., Fochesatto, J., Brioude, J., and Bower, K. N.
Abstract:: The VAMOS Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx) was an international field program designed to make observations of poorly understood but critical components of the coupled climate system of the southeast Pacific. This region is characterized by strong coastal upwelling, the coolest SSTs in the tropical belt, and is home to...

Selenium Supplementation Restores Innate and Humoral Immune Responses in Footrot-Affected Sheep

Creator:: Hall, Jean A., Vorachek, William R., Stewart, Whitney C., Gorman, M. Elena, Mosher, Wayne D., Pirelli, Gene J., and Bobe, Gerd
Abstract:: Dietary selenium (Se) alters whole-blood Se concentrations in sheep, dependent upon Se source and dosage administered, but little is known about effects on immune function. We used footrot (FR) as a disease model to test the effects of supranutritional Se supplementation on immune function. To determine the effect of Se-source...

High-Density SNP Genotyping of Tomato (Solanum lycopersicum L.) Reveals Patterns of Genetic Variation Due to Breeding

Creator:: Sim, Sung-Chur, Van Deynze, Allen, Stoffel, Kevin, Douches, David S., Zarka, Daniel, Ganal, Martin W., Chetelat, Roger T., Hutton, Samuel F., Scott, John W., Gardner, Randolph G., Panthee, Dilip R., Mutschler, Martha, Myers, James R., and Francis, David M.
Abstract:: The effects of selection on genome variation were investigated and visualized in tomato using a high-density single nucleotide polymorphism (SNP) array. 7,720 SNPs were genotyped on a collection of 426 tomato accessions (410 inbreds and 16 hybrids) and over 97% of the markers were polymorphic in the entire collection. Principal...

Non-Invasive Sampling of Schistosomes from Humans Requires Correcting for Family Structure

Creator:: Steinauer, Michelle L., Christie, Mark R., Blouin, Michael S., Agola, Lelo E., Mwangi, Ibrahim N., Maina, Geoffrey M., Mutuku, Martin W., Kinuthia, Joseph M., Mkoji, Gerald M., and Loker, Eric S.
Abstract:: For ethical and logistical reasons, population-genetic studies of parasites often rely on the non-invasive sampling of offspring shed from their definitive hosts. However, if the sampled offspring are naturally derived from a small number of parents, then the strong family structure can result in biased population-level estimates of genetic parameters,...

Recruitment, Growth and Mortality of an Antarctic Hexactinellid Sponge, Anoxycalyx joubini

Creator:: Dayton, Paul K., Kim, Stacy, Jarrell, Shannon C., Oliver, John S., Hammerstrom, Kamille, Fisher, Jennifer L., O'Connor, Kevin, Barber, Julie S., Robilliard, Gordon, Barry, James, Thurber, Andrew R., and Conlan, Kathy
Abstract:: Polar ecosystems are sensitive to climate forcing, and we often lack baselines to evaluate changes. Here we report a nearly 50-year study in which a sudden shift in the population dynamics of an ecologically important, structure-forming hexactinellid sponge, Anoxycalyx joubini was observed. This is the largest Antarctic sponge, with individuals...
